The "how to qualify for the California ADU grant" guides all over the internet describe a program that closed at the end of 2023. That is not the homeowner's fault. You Google it, you read three pages that all say "here is who qualifies," and you reasonably assume the money is sitting there. It is not, and the state says so on its own page. Everything below is current as of September 11, 2026, and every figure is dated and linked to its official source, because I build ADUs, I do not lend money, and these programs move.
The CalHFA grant has been closed since December 28, 2023
CalHFA's ADU Grant Program has been closed to new applications since December 28, 2023. The state's own CalHFA ADU Grant page still carries the same notice as of September 11, 2026: the latest round of ADU funding has been fully allocated. There is no new round, no waitlist, and no open application.
One thing on that page matters more than the closure notice, and I want to state it plainly. CalHFA warns: "If anyone approaches you saying they can help you get an ADU Grant, it is a financial scam." Nobody can get you a grant that is not accepting applications. So if someone pitches you an "I can get you approved for the $40,000" service, or offers to add you to a grant waitlist, that is a red flag, and CalHFA asks you to report it. The only trustworthy status for this program is the one on calhfa.ca.gov/adu itself.
What the CalHFA grant actually was
When it was funded, the grant reimbursed up to $40,000 of pre-development and non-recurring closing costs. That covered the soft costs that scare people off early: architectural design, permits, soil tests, impact fees, property surveys and energy reports. It never paid for hard construction, meaning no labor and no materials. It was a genuinely useful program, and I had clients use it. The problem is not that the grant was bad, it is that it ran out of money.
The final round was income-limited to 80% of Area Median Income, effective November 1, 2023, a cut from the initial round. Those limits were county-specific, so there was never a single number, and I am not going to print a current dollar figure here. Some secondary pages quote much higher "moderate-income" amounts that I could not confirm against CalHFA's official file. If you want the real numbers for a future round, they live in CalHFA's official ADU income limits PDF, and that is the only place I would trust them. One more detail people miss: the grant flowed through CalHFA-approved lenders, not direct applications. You did not apply to the state, your lender rolled the eligible costs into a construction loan and sent the application in.
The live California alternative: San Diego's ADU finance program
Before the terms, the trade-off, because it is the whole story. The strongest still-published California program is the San Diego Housing Commission's ADU Finance Program, and its cheap money comes with a 7-year affordability covenant that caps your rents at households earning 80% of Area Median Income. That covenant is the cost of the subsidized rate. If you were planning to rent the ADU at full market rent from day one, this program is not free money, it is a rent restriction in exchange for a low rate. Decide whether that trade works for you before you fall for the interest number.
With that said, the terms are genuinely strong. Per the San Diego Housing Commission's ADU page and its adu.sdhc.org site, the program offers a construction-to-permanent loan up to $250,000 at 1% fixed during construction, converting to a 4% fixed 15-year permanent mortgage, with up to roughly 75% loan-to-value and free technical assistance. It serves owner-occupants up to 120% AMI, looks for around a 680 minimum credit score, and asks the owner to contribute about 1% of the loan amount. One honest caveat: the permanent-rate, LTV, credit-score and AMI specifics come from SDHC program materials and secondary summaries, so confirm them against SDHC's current term sheet before you count on any single figure. All of this is as of September 11, 2026.
The other California programs, briefly and honestly
A few smaller local programs exist, and a couple of things that get sold as grants are not. Here is the California picture side by side, all as of September 11, 2026. Treat status and funding as things to re-verify with each program directly, because local money opens and closes without much notice.
| Program | What it is | Key terms | Status (as of September 11, 2026) |
|---|---|---|---|
| CalHFA ADU Grant (statewide) | Up to $40,000 to reimburse pre-development soft costs | Never paid for hard construction; final round used an 80% AMI limit | Closed to new applications since December 28, 2023 |
| San Diego Housing Commission ADU Finance Program | Construction-to-permanent loan up to $250,000 | 1% fixed during construction, converting to 4% fixed 15-year; 7-year affordability covenant capping rents at 80% AMI | Published terms; verify current funding |
| LA County Second Dwelling Unit pilot | $75,000 forgivable loan for a new ADU | Tied to renting to a homeless or voucher household for 10 years | Not accepting applications |
| Napa County Affordable ADU forgivable loan | $45,000 to $105,000 forgivable | 5-year affordability covenant | Local program; verify current funding |
| West Hollywood Affordable ADU pilot | Up to $150,000 construction loan at 1% | Affordability-restricted | Local program; verify current funding |
| Orange County Housing Finance Trust | Deferred and partially-forgivable loans | Local eligibility rules | Local program; verify current funding |
Two clarifications the older guides get wrong. First, the LA County Second Dwelling Unit pilot, a $75,000 forgivable loan, was tied to housing a homeless or voucher household and is not accepting applications, so do not budget around it. Second, LA city's ADU Accelerator is a tenant-matching program that pairs you with a housing-insecure renter, not build money. If anyone pitches the Accelerator to you as a construction grant, they are wrong. For the wider state list, California HCD keeps a directory of ADU funding and financing resources that it actually maintains, which is more than most grant content can say.
Financing an ADU when there is no grant
Here is the part worth your time. Most California ADUs get built with home equity plus a construction loan, not a grant, and honestly that is more durable than a one-time reimbursement anyway. The bigger 2026 shift is not a grant at all: all three major loan channels now let you count ADU rental income toward qualifying on a one-unit primary residence, which changed who can get approved in the first place. That single rule helps more California homeowners than the CalHFA grant ever did.
I will not repeat the full loan breakdown here, because it has its own home. Read the honest version of HELOCs, home equity loans, renovation loans, construction-to-permanent, and those 2026 rental-income rules on our ADU financing hub. If you are not in California, our guide to ADU grants by state covers Massachusetts, Boston, Colorado and Portland, plus the states where the "grant" is a myth.
Whatever you finance it with, the loan has to cover a real build number, so pin that first. Our California ADU cost data and Los Angeles cost breakdown are more useful than any national average, our Data Hub tracks the ranges as they move, and you can price a build for your lot in a few minutes.
Frequently asked questions
Is the California ADU grant still available in 2026?
No. The statewide CalHFA ADU Grant has been closed to new applications since December 28, 2023, and as of September 11, 2026 there is no announced new round. CalHFA's own ADU page still carries the notice that the latest round of funding has been fully allocated, with no waitlist and no open application. If you built a plan around that $40,000, the honest move is to re-plan without it rather than wait on a relaunch that has no date.
Who qualified for the CalHFA ADU grant when it was open?
When it was funded, the grant reimbursed up to $40,000 of pre-development soft costs like design, permits, soil tests and impact fees, and it was income-limited. The final round used a limit of 80% of Area Median Income, effective November 1, 2023. Those limits were county-specific, so there was never one number, and I am not going to print a current figure here because the program that used them is closed. If a future round opens, CalHFA publishes the official county limits, and that is the only place I would trust them.
Are there scams targeting people who want the ADU grant?
Yes, and CalHFA warns about this directly. The state says plainly that if anyone approaches you offering to help you get an ADU Grant, it is a financial scam. Nobody can get you a grant that is not accepting applications, so treat any "I can get you approved" pitch as a red flag, and treat any "join the grant waitlist" form as lead capture, not a government list.
What California ADU programs are actually live now?
The live help is local, not statewide. As of September 11, 2026, the San Diego Housing Commission runs the strongest still-published California program: a construction-to-permanent loan up to $250,000 at 1% during construction. The trade-off is a 7-year affordability covenant that caps your rents. A handful of smaller county and city programs exist too, in places like Napa, West Hollywood and Orange County, while the LA County forgivable-loan pilot is not accepting applications. Confirm current funding with each program before you count on it.
Will the CalHFA ADU grant come back?
Maybe, but there is no announced date, so do not plan around it. Reviving a program like this takes a new state budget allocation, and none has been confirmed for a fresh round as of September 11, 2026. CalHFA has said only that it may return in future funding cycles. If it does return, it will likely be income-limited again and go fast, so the smart move is to be build-ready now rather than wait.
If you were counting on that $40,000, take a breath, then re-plan without it. Waiting on a relaunch with no date is not a strategy, it is a stall. Pin your real number first, check whether the ADU rental-income rule gets you over the qualifying line, and only then shop the loan. Start with a cost estimate for your lot.
